WATER REACTION TANK
A water reaction tank for reacting water containing suspended solids with a flocculant includes a housing having an input, an output, and a water flow path between the input and the output. The flow path has a mixing section and a reaction section. Sealable flocculant ports are provided for inserting a flocculant into the mixing section of the housing. Each of the mixing section and the reaction section contains baffles. The mixing section baffles encourage turbulent flow to increase contact with the flocculant, and the reaction section baffles encourage turbulent flow and increase the length of the water flow path.

A tank used to react water with a flocculant to clarify the water.
BACKGROUNDRegulations require that water from construction or other sites must be cleaned to a certain degree before being returned to the environment. Flocculants may be used to cause suspended fine particles to settle out of the water.
SUMMARYThere is provided a water reaction tank for reacting water containing suspended solids with a flocculant. The water reaction tank comprises a housing having an input, an output, and a water flow path between the input and the output. The flow path has a mixing section and a reaction section. Sealable flocculant ports are provided for inserting a flocculant into the mixing section of the housing. Each of the mixing section and the reaction section contains baffles. The mixing section baffles encourage turbulent flow to increase contact with the flocculant, and the reaction section baffles encourage turbulent flow and increase the length of the water flow path.
According to another aspect, there is provided a method of reacting water having suspended solids with a flocculant. A reaction tank is provided, comprising a housing having an input, an output, and a water flow path between the input and the output, the flow path having a mixing section and a reaction section, sealable flocculant ports for inserting a flocculant into the mixing section of the housing, where each of the mixing section and the reaction section containing baffles, the mixing section baffles encouraging turbulent flow to increase contact with the flocculant, the reaction section baffles encouraging turbulent flow and increasing the length of the water flow path. Flocculant is inserted into the mixing section through the sealable flocculant ports. Water is pumped into the reaction tank at a rate such that the turbulent flow caused by the baffles allows the flocculant to react with the suspended solids in the reaction section, and such that the water exits the output of the housing prior to the flocculated solids substantially settling from the water.

In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
The following claims are to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, and what can be obviously substituted. Those skilled in the art will appreciate that various adaptations and modifications of the described embodiments can be configured without departing from the scope of the claims. The illustrated embodiments have been set forth only as examples and should not be taken as limiting the invention. It is to be understood that, within the scope of the following claims, the invention may be practiced other than as specifically illustrated and described.
Claims
1. A water reaction tank for reacting water with a flocculant, the water containing suspended solids, the water reaction tank comprising:
- a housing having an input, an output, and a water flow path between the input and the output, the flow path having a mixing section and a reaction section;
- sealable flocculant ports for inserting a flocculant into the mixing section of the housing;
- each of the mixing section and the reaction section containing baffles, the mixing section baffles encouraging turbulent flow to increase contact with the flocculant, the reaction section baffles encouraging turbulent flow and increasing the length of the water flow path.
2. The water reaction tank of claim 1, wherein the flocculant ports are sealable.
3. The water reaction tank of claim 1, wherein the mixing section is disposed above the reaction section within the housing, the mixing section and the reaction section being connected by a vertical flow port.
4. The water reaction tank of claim 3, wherein the reaction section comprises more than one vertically stacked level within the housing.
5. The water reaction tank of claim 1, further comprising sea table flushing ports for permitting cleaning fluids to be flushed through the housing when opened to remove any debris or solids in the tank.
6. The water reaction tank of claim 5, wherein the flushing ports permit cleaning fluids to be flushed through the housing perpendicular to the flow path direction such that the cleaning fluids are not significantly impeded by the baffles.
7. The water reaction tank of claim 1, wherein the housing has an attachment for securing a solid block of flocculant or a flocculant in a porous container within the mixing section.
8. A method of reacting water having suspended solids with a flocculant, comprising the steps of:
- providing a reaction tank comprising: a housing having an input, an output, and a water flow path between the input and the output, the flow path having a mixing section and a reaction section; sealable flocculant ports for inserting a flocculant into the mixing section of the housing; each of the mixing section and the reaction section containing baffles, the mixing section baffles encouraging turbulent flow to increase contact with the flocculant, the reaction section baffles encouraging turbulent flow and increasing the length of the water flow path;
- inserting flocculant into the mixing section through the sealable flocculant ports;
- pumping water into the reaction tank at a rate such that the turbulent flow caused by the baffles allows the flocculant to react with the suspended solids in the reaction section, and such that the water exits the output of the housing prior to the flocculated solids substantially settling from the water.
